The 1st Robot Survival Game took place in Akihabara, Tokyo (July 19, 2010)

The 1st Robot Survival Gametook place at ASOBITCITY in Akihabara, Tokyo on July 19th, 2010. Variety of robot, not only multi-legged robot such as 4-legged, 5-legged, 6-legged with wheels but also mobiles such as tank with 4-wheels or caterpillars joined the game.

The organizer who were Tanaka-san (Dainihon-giken) and Bishii-san (Asakusa-giken)announced on Dec 4th, 2009 that they began to make multi-legged robots for robot survival game with toy gun and sensor for detecting the impact, which were controlled using image monitor such as Mech Warfarein U.S.A. The movement of making multi-legged robot in Japan began from this announce.

Trials were held twice for getting information of the robot survival game such as gun-shoot range of height and radio control and camera system without confusion. The 1st trailtook place at the office of Dainihon-giken in Mitaka City, Tokyo on April 10th and the 2nd one at ASOBITCITY in Akihabara and at Kanto Trainning Meeting in Minami-senju, Tokyo on June 13th, 2010.

Main regulations of the robot survival game are as follows;
1) Mobile bodies are not only multi-legged robot or biped robot but also mobile with wheel or caterpillar.
2) Weapons are toy-gun under 0.1 J and/or the other shooting system.
3) Equipped stopping mechanism of the body by gun-hit sensor using a solar battery covered with tinfoil(6 x 6 x 6 cm cubed or 5 x 6 x 7 cm).
4) Robot control has to be done with the image on PC from the camera attached on the robot.
5) Participants have to handle toy-gun carefully and put protector on eyes.

There are 18 enrollments for this robot survival game. Eight robots (including mobile bodies with wheels or caterpillars) with full equipments for the regulation joined the 1st Robot Survival Game. The other members were in the course of making equipments for the survival game such as gun-shooting and gun-hit sensor systems.

Multi-legged robot is stable to walk compared with biped robot and even low powered servo motor can move the body. It is not so hard for biped robot builders to make a new multi-legged robot. Biped robot builders also have a lot of idle controller, servos, arms and parts.

However, it is not so easy even for robot builders to make these robot survival game systems. Participant has to make his mobile body, gun-shooting system, gun-hit sensor and camera system. It is also necessary for correct gun-shooting to make a laser beam aiming system. Koizumi-san, a member of the robot survival game, designed the electric circuit for gun-shooting system and gun-hit sensor system. As the circuits are not sold on the market except for electric parts, member has to make these electric circuits by himself.

Eight robots were divided into two teams. Each team reader was Igaa-san and gons-san respectively.
Members of Igaa team are as follows;
`Vanga`, 6-legged with wheels robot was custom-built by Igaa. It could move very fast using wheel system.
`Yabusame`, 4-legged robot was custom-built by Mota.
`Arnold Stallone`, 4-legged turtle robot with KCB-3WL, which was a new board for remote controlling robot system from KONDO by watching image around the robot on PC, with double guns system was custom-built by Noborizaka.
`Danga`, mobile with caterpillar such as tank was custom-built by Igaa.
Members of gons team are as follows;
`Denryu’ with 4 wheel body was custom-built by gons.
` BLACK TIGER L45`, 5-legged robot was custom-built by IKETOMU. As it was based biped robot body and using high power servo motor KRS-4013HV, the mobility was high compared with other multi-legged ones.
`Goryu`, mobile was custom-built by Koizumi.
`Osaru-2.5gou`, mobile with caterpillars attached a rubber band frotress was custum-built by Osaru.

Setting up camera control system behind the field

Tanaka-sanplaned field layout to use long shooting range valuable, field was divided into 4 parts as A to D. In the A & D parts, high and big obstacles were set for not to recognize each other till the moment they saw each other as street fighting. In the B &D parts, low and small obstacles for barricade were set, where they can see each other but they have to move for shooting.
Tanaka-san also planned games as follows;

[Combat Shooting]
Practice game for trainning of shoot skill. In the C & D field, player moves to the No.1 shooting place from the starting point and shoot the target. After shooting down the target, player moves to next place and shoot the target. Winner is the shortest time player for shooting down 3 targets. The target is a cut 1 L milk paper pack. Player has to go through a wire gate or to push down a flag for getting to the shooting place.

[Sparring]
Practice game for team member. Sparring takes place in the A(D) field or B(D) field. Sparring takes place between a expert and a beginner for 3 minutes. The Expert cannot shoot and just run away around the beginner shooting.

[Handicapped game]
Practice game for team leader vs other team members for 3 minutes in the C & D field. During the first 2 minutes and 30 seconds, team leader cannot shoot and run away, other team members shoot leader. During the rest 30 seconds, the leader can shoot other team members and other members cannot shoot. All robots put on the diagonal (line) at the starting time to prevent from ending the game in a short time.

[Team game]
Each team has A & B or C & D fields as territory. Robots can put in the A & D field at the beginning of the game. Game time is 5 minutes.

1. Destroy the enemy completely
Each team fights to destroy the enemy completely within 5 minutes. The winner team is having larger number of survival robot after 5 minutes.

2. Flag fight
Each team fights to shoot down flag in the enemy territory as the combat shooting. The winner is the team shot down the enemy flag within 5 minutes or the team which has larger number of survival robot after 5 minute in the case of each flag does not shoot down within 5 minutes.

[Fight a duel]
Just 2 robots fight in the field. Using of field and fighting time is free.

Before above survival games took place, hit sensor ajustment of all robots for same sensitivity was carried out.

Survival game between 2 teams was carried out. The 1st game was carried out without camera system. The 2nd game was carried out using camera image on PC.

[Sparring]

Practice game for team member. Sparring takes place in the A(D) field or B(D) field. Sparring takes place between a expert, Vanga and a beginner, Yabusame for 3 minutes. The Expert cannot shoot and just run away around the beginner shooting.

[Handicapped game]

Practice game for team leader vs other team members for 3 minutes in the C & D field. During the first 2 minutes and 30 seconds, team leader cannot shoot and run away, other team members shoot leader.

About Me

I have been enjoying biped robot since 2004, when KHR-1 was put on the market, and collecting information of hobby robots. I would like to upload information about hobby robots in Japan for the hobbyists of biped robot all over the world. As my ability for uploading is limitted, I will introduce just news of product, kit or parts and information of competition etc. with picutures or videos.
